To all whom/15 muy cancers/Ll' sf, Y.

Be it known that l, NMi-mic Roeniinnno, a citizen of the 'United States, and/'reside/nt of North l'arrytown, county of Weetchester State of New York, have invented ,certain neu and useful lnuiu'ovelnents yin LiquidH Fuel Burners, of which the following n specication. j y

This invention relates to burners for oil and other liquid fuel.

More particularly the invention comprises un inflow element connected to the source of liquid i'uel supply. ports for the adniiesion of air to the bindung*duel, and ineens i'or controlling the-resulting ilaine :ted hy the incl. ihi-'ahly,=tlie iniiow element conrprises a t sli-shaped receptaele into wieh` the li'iuid ,ifuel :flows from on inlet openingr disposed ahoije the bottom of such receptacle', and the 'ninis supplied through one or inore openings in a hood-like inclosure disposed :thove .such receptacle. The means for controlling the resulting flame or fia/mes inn-5i comprise one or more deflectorstdieposed in a ,determined position relative )lo vthe/'fuel in/let element. The character di: theigtlznuey is determined lloy the structure of the de flcote1'.tl1e rela* tion of the dellector to the Y, nel inlet' ele-r ment andsuclrother Vurialilel relationship as will appear more fully hereinafter.

@ther ,features and objects of uri/inven-4 tion Willhe more fully understood from the following'. description and the eccomi, panying drawings, in whichu v Figure l shows one forni of my invention, the portion to the left benign, side elevation and that to the right heingi t central sectional elevoatiou on the line lnj of Fig. 2, looking iIi the direction offlzh'e amori; lFig. 2 is a top plan View of the'eal'ne. ornitting the top defleetor; Fig. 3 is an end val tion; and Figli ie o central sectional elevation on the line l-45 oi' llig. 2.

Referring; .to the drawings. the burner conlprise-,e ,inlet l oonuectedto' the source of liquid fuel supply bythe piping' 2. Preferably, 'the inlet l is a piped/having its lower" endi @crew threaded to the piping Q, theynpper flattened end -veofpipe 3 being element 6, positionedat or toward the center of the dish-shaped receptng'cle l havingfii, curved bottom. It is preferred to flattery-j the end 5 to lforni a` Suhstantinlly rect-angu- K lar opening, the sides of which are disposed i substantially parallel to the contour of the Substantially rectangular reeeptz'icle 7. ne shown, wherein)7 to secure uniform dow ot' the luidirol'n `the outlet 5 into the reeeptacle 7. The lion' of the liquid fuel troni the source of `supply, say a tank, is controlled by' t suitable cock or valve, and the fuel thus control/led flows over and down the eidee oil curi/ed cone-like element 6 into the curved bottom of the receptacle 7. l/Vhen the burner isignited, the fuel flowing out of the outlet heated and will burn the a rea. oi hurning fuel extending over the iuel contained in the receptacle 7.

Air for eil'ecting and completing the coinn bustier of the fluid fuel Aenters the openings 8j 9, communicating With the interior ot ihn hood l0. rlhe hood l() is preferably supported hy the extension 1l projettinei troni lthe upper edge of the receptacle T. l have shown 'the extension to loc Substantially revA tangular in shape extending laterally on all tour sides of the receptacle 7` and having strips l2 for retaining' the hood l() in posiu tion thereon." The hood l0 may he made of corresponding halves 13, 14, with overlapping flanges 15. along' the meeting edges.

The-hond haliies ure shown to he held tog'otlier,l by boltsA 17, l The hood may he made offcist iron, or .steel or the like, and by the use ot' the overlapping flanges and lthe holo:` or the like the hood parts will he prevented freni siucacling` due to high temperature, l have shown the hood l0 to he formed o1 a central dome 18 and hulged eide (ifllainhers 19, 1 9, although such arrangement may he varied as will he understood h v those skilled in the art.

-ln the specific ormngenient thus described, `the air entering;1 the openings 5%. Sl. flows through the respective hulpfed cham here 19, 19, into the respective connecting" passages 20, 20, and thence into the dome chamber 18 of *relatively large volume. .v

thence downwardly through the large open-- ing 2l formed by the dependingu ring' or lip 22 and finally into with the hot vapor of the heated fuel. its one form 0i' means for controlling the re suit-ing fla-1nd l have indicated the dede-etoi- 25 supported hyfi" elzfitendingr from one side of thehoodfllllf:Such deilecl'or 23 is euitahle when it is desired to heat :1 linking oven suitably positioned on the same side of the hood 10 as the defiector 23. The relation of the deflector 23 to the fuel supporting:

Intimate inintn i il il noeeeea in a deine suitable for heating a Water back oi' like devise by means ci relatively localized dame. v

lt will be noted that the deleetor 23 forsecuring a relatively Wide combustion area is disposed at a greater distance from the receptacle 7 than the deiieetoi 2li, the latter effecting a llame of relatively narrow combustion area,

When it is desired to employ burner to heat a furnace or like device utilizing a 'Vj-e i extended llame sueh flame will by omittine" the deleotors 23 and i ing; the detlnector shown in the an inverted cone supported above 1G, by the circular llange 27 enupivardly extending boss 28 on uppoiting means for the deeetor 25 may be en'iployed.

The deilectors 23, 2l, may be removably supported at the sides of hood l0, or may be integally with the respective hood halves 13, lf desired, the flow of the air into the openings of the hood may be. regulated by a suitable regulator. Ordinarily, the proper flow or" air will be controlled automatically by the hood comprising the central dome chamber 1S of relatively large volume and subjected to high heat into which the air flows from one or more sides iii-oni the bulged chambers lll, 19, through the somewhat restricted connecting passages 20, :20, l have indicated the burner :is of a geneial rectangular Snape, but such shape may be varied to attain the objects desiied. lt is desirable to make all portions of the an? inflow and outlow openings With flaring edges and the air chambers with rounded surfaces without corners, whereby iidiilg surfaces are presented to the air flowt lt is also advantageous to give the cone-like element a curved surface, and to 'What l claim and desire to. secure by Letters lJ-utent is I l. in a burner or the like, the combination.

"of an inlet, a receptacle for supjljiovtinsr the fuel disposed below the opening of said inlet, an air hood comprising a doine portion of'frelatively large volume and an air inlet portion, said dome portion being disposed above said receptacle and having an air outlet adjacent said receptacle, said domeinoludinp; its air outlet being; free from obstr` :m parts, and a delector disposed above and spaced from the sides of said receptacle,
